SNOW- PLOW.

SPECIPICATIONforming part of Letters Patent No. 346. dated August 3. 1886- Application filed April 9, 1886. SerialNo. 198,364. (No model.)

T0 aZZ whom it may concern:-

Be itknown that I, PETER B. BRAZEL, a citizen of the United States, residing at Oheboygan, in the county of Oheboygan and State of Michigan, have invented certain new and useful Improvements in Snow-Flows; and I do hereby declare the following to beafull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improved snow and ice plow; and it consistsin the construction and arrangement of the parts, which will be more fully hereinafter described, and pointed out in the claims.

One object of my invention is to provide means whereby the parts of the plow may be readily raised or lowered from and to the ground by suitablelevers and cranks, the whole being readily operated, easily handled and transported.

Afurther object of my invention is to so construct the plow that it shall be adapted for use upon sidewalks, street-railways, race-courses, and driving-parks, the parts of the plow being so arranged that the snow or ice will be pushed or thrown to one side of the walk, both by the main plow and a supplementary scrapingplow in the form of a wing.

A still further object of my invention is to construct and arrange the main plow upon a.

single central beam, with bob-sleds secured to each end thereof, said bob-sleds being provided with suitable mechanism for preventing the sled from slipping from its true line of draft.

I attain these objects by the construction of plow illustrated in the accompanying drawings, wherein like letters of reference indicate similar parts in the several. views, and in which- Figure 1 is a perspective view of my improved snow-plow. Fig. 2 is a bottom plan view of the plow. Fig. 3 is an end elevation of the rear bob-sled.

A indicates the central supporting-beam, to the front end of which is attached a bobsled, B, which is pivotally connected to the said central beam, A. To the rear of the beam A another bob-sled is connected, which has a top platform, bb, on each side of thesaid beam.

In thecentral part of the device a metallic plow,C, is mounted, projecting on each side of the central beam, A, and whose upper portion is formed on an incline. This plow O is in the form of a mold-board, and is constructed of sheet metal of suitable thickness to resist the strain thereon. It is slotted, as at 0, so that the central beam can fit therein, and two angular extensions, 0 c, are formed with the said mold-board, on the rear side, extending from near the bottom up to the top portion thereof, and thence back on each side of the central beam, A, and secured thereto. Thus the plow is strengthened, and is further re-enforced by bracerods 0 a, connected to the outer sides, and to the angular extensions 0. These extensions 0 have small flanges c c inclined inward, which engage with relativelybeveled strips a a, secured to the central beam, forming therewith a dovetailed slide, for purposes which will be more fully hereinafter described.

To the angular extensions 0 are two standards, 1 1, which extend above the upper edge of the central beam, A, and are connected at their upper parts by a cross-rod, 2. Eccentrically mounted on this crossrod 2 is a lever, 3, adapted to raise and lower the plow 0, through the medium of the extensions 0'. In the end of the lever 3, below where it is mounted on the cross-rod 2, a cam-slot, 4, is formed, which is engaged by a link, 5, which embraces the upper part of the beam A, and is pivoted thereto. The end of the lever 3, where it is slotted, is somewhat enlarged and circular in form, and continually bears upon a metallic plate, 6, mounted on'the top edge of the central beam, the other end of the said lever being formed as an operating-handle, 7. WVhen the handle 7 is depressed, the end of the lever 3 turns on cross-rod 2, and the link 5 rides down to the lowest point of the camslot 4, and the two standardsl 1 are raised, which in turn draw on the extension 0,'connected to the plow G, and clear it from the ground. When the standards are operated through the means just described, they slide upwardly and downwardly on the blocks a a, connected to the beam A, being in continual engagement therewith. WVhen it is desired to depress the moldboard 0 and put it in a position to operate, the handle 7 is raised, the link 5 rides easily in the cam-slot 4,and the mold-board is depressed,

- which is constructed in the form of an angular plate.

On the inside of the runners of the rear bobsled, B, supplementary runners E E are mounted. (See Figs. 2 and 3.) The inside of the outer runners are provided with projections e e, which engage with slots 6 e in the sup plementary runners E E, and on which the said runners E have free vertical movement.

When it is desired to raise the rear sled and its operating parts from the ground duringthe transportation of the plow from one place to another, the supplementary runners E are forced down by means of levers E E',mounted in the platform of the bob-sled B on each side of the central beam, said levers engaging the tops of the runners E. When the runners E are depressed, they are held in a lowered position by the ratchet-strips 11, pivoted to the platform, engaging with the metal strips 12 on the said levers. The lower ends of the levers E are rounded, so as to give an easy motion thereto in the operation of depressing the runners E. When it is desired to allow the runners E to be forced back in order to operate the plow, the ratchets 11 are disengaged from the levers E, and the pressure of the plow forces the said runners back into a position on a level with the runners of the bob-sled B.

In the rear inner side of the bob-sled B a cross-rod, 13, is mounted,which has two ratchet-wheels, 14 14, mounted on each side thereof adjacent to the runners of the said bob-sled. In the central portion of this cross-rod a plain beveled-edged wheel, 15, is mounted, having the largest plane or resisting surface against the pressure of the snow. These wheels prevent any tendency on the part of the plow to depart from its true line of draft by the wheel 15 cutting into the snow or ice, and the toothed wheels 14. 14 acting as creepers. The bobsled B is in like manner provided with a crossrod, 16, but has only one plain central wheel, 17, mounted thereon, similar to the wheel 15. This cross-rod 16 and its wheel 17 are mounted above the lower surface of the runners of said bob sled, for the reason that the snow which has not at that point been cleaned away by the plow is deeper, and as the runners of the bob-sled B sink therein the wheel 17 also is partially embedded, and prevents the plow from turning to one side or the other when not desired.

The front portion of the plow is provided with a drivers seat, 18, mounted on the top of a post or standard, 19, said plow being also provided at this point with a triangular platform, 20, which rests over the forward bobsled, B.

When it is desired to use the plow, the moldboard 0 is forced down by means heretofore described and the wing D forced outward. The snow is turned over by the highest portion of the mold-board formed by the incline, and that portion which may accidentally pass over the top of the mold-board or around the same is taken up by the wing D and the entire pavement cleaned. Only one wing is necessary, owing to the fact that the discharge side of the mold-board is to one side of the plow proper, and the wing is therefore only needed on that side to clean what may be left by the said mold-board.

It is obvious that many changes in the construction and arrangement of the parts could be made and substituted for those shown and described without materially departing from the nature and principle of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isr 1.
